No. 319,271 7 Claims. (Cl. 101-32) The present invention relates to printing processes, and more particularly to the producing of relief impressions on paper and printing the raised portions thereof by an offset process or other similar printing operation.

The present invention contemplates the producing of raised image impressions and the applying of ink to the raised portions similar to that obtained by embossed printing by use of printing plates having the image in relief as by photo-engraving and eliminating the use of relatively expensive metallic male and female dies as are normally used for embossed printing, In the embossed printing as heretofore practiced, it has been necessary for the printer to obtain metallic male and female dies prepared by engraving, etching or by other hand or mechanical processes which are time-consuming and costly. The high cost of embossing dies and the printing operations using same result in the printed product being expensive and almost prohibitive with small quantity jobs.

The principal objects of the present invention are to provide a printing process for obtaining printed images in relief on paper or sheet material with comparatively inexpensive printing plates on which the images are in relief; to provide such a method wherein two male or positive plates having the images identical and in relief are used with an offset process machine wherein one plate is inked and transfers an ink image impression to the surface of a blanketed roller and the second plate is registered with said inked image impression with paper squeezed therebetween to form the paper toward the blanketed rotler in raised configurations of the image and transfer the ink from the impression the blanketed roller received from the first plate to the raised portions of the image on the paper; to provide for printing of such images in relief by means of positive plates having the raised images thereon wherein one of the plates is applied to a plate cylinder portion and the other plate is applied to an impression plate cylinder portion of an offset printing machine with the image on the plate applied to the impression portion having the image in greater relief than on the plate applied to the plate cylinder portion; to provide such a process wherein the plate applied to the impression cylinder portion is transparent and an ink impression of the image is transferred from the plate on the plate cylinder portion to the blanketed roller and then to the impression cylinder portion and said transparent plate desired relative position on which the image is to be applied.

registered with said ink impression on the impression cylinder portion and adhered thereto by double face pressure-sensitive adhesive therebetween; to provide such a process wherein the printing plates have margins extending beyond the images thereon and having centering indicia in relief on said margins for facilitating obtaining registry in the product, said indicia being removed after registry is obtained whereby only the desired image is placed on the printed product; and to provide a method and means of forming and printing images in relief on paper that is economical andcapable of being performed on conventional olfset printing machines.

Other objects and advantages of this invention will become apparent from the following description taken in connection with the accompanying drawings wherein are set forth by way of illustration and example certain embodiments of this invention.

FIG. 1 is a partial vertical sectional diagrammatic view through a two cylinder offset printing machine with plates mounted thereon for printing relief images.

FIG. 13 is a diagrammatic view of a three roll offset press with printing and impression plates with the image in relief thereon positioned on the plate roll and impression roll respectively.

Referring more in detail to the drawings:

One form of apparatus for printing images in relief on paper, according to the present invention, is shown partially in section and diagrammatically in FIG. 1 with sheet material such as paper sheets 1 to be printed shown travelling on a feeding mechanism such as a belt 2 in the direction indicated by the arrow 3 to pass between the cylinder or roll portions to effect the printing operation.

The apparatus preferably operates on the offset printing process and the apparatus illustrated in FIG, 1 is a tWo cylinder or roll machine, wherein the cylinder or roll 4 has a plate roll portion 5 and an impression roll portion 6 on opposed portions of the cylinder. The apparatus includes a blanketed cylinder or roll 7 having a rubber or otherwise resilient sheet or layer 8 on the periphery thereof that is a resilient blanket for receiving ink impressions of an image to be printed on the paper 1 and transfer said impression to said paper as later described. The roll or cylinder 4 is mounted on a shaft 9 and is fixed relative to a gear 10 meshing with a gear 11 fixed relative to a shaft 12 carrying the blanketed roll 7, the gears 10 and 11 being of a relative size' whereby the blanketed cylinder or roll 7 rotates two complete revolutions to one revolution of the cylinder 4. In the structure illustrated, the cylinders are driven in a conventional manner as by a chain 13 operatively connected to a source of power (not shown) and drivingly engaging a sprocket 14 fixed relative to the shaft 12 to rotate the cylinders 4 and 7 in the direction shown by the arrows 15 and 16 respectively.

The apparatus also includes an inking unit 17 having a plurality of rolls including a form roller 18 for applying ink to a printing plate 19 in a conventional manner, the inking unit being movably mounted or arranged whereby the form roller 18 is spaced from the periphery of the cylinder 4 as the impression plate portion 6 passes thereunder and is moved to effect engagement of the periphery of the form roller with an image on the printing plate 19 on the plate roller portion as said plate roller portion passes under said form roller 18. In the structure illustrated, there is a draw sheet or member 20 removably mounted thereon and extending over the impression roll portion 6 with one end extending inwardly from the periphery thereof and secured to an extension 21 by suitable fastening devices such as screws 22. The other end of the draw sheet has a plurality of apertures 23 that are engaged over hooks or other fasteners 24 on a bar 25 that is movably mounted on an extension 26 at the other end of the portion 6 with adjusting screws 27 for moving said bar 25 to apply tension on the draw sheet to pull it down against the periphery of the roll portion 6. A sheet of paper 1 to be printed must pass between the impression roll portion 6 and the blanketed roll 7 and be squeezed therebetween and to vary or adjust the squeezing pressure packing 28 is positioned between the draw sheet 20 and the surface of the impression roll portion 6. This packing consists of a plurality of sheets of different thicknesses whereby the combined thickness positions the periphery or outer surface 29 of the draw sheet on a desired radius from the shaft 9 so it, with the particular thickness of the paper to be printed, will provide the desired squeezing pressure on said paper and also preferably such that the effective radii of the blanketed cylinder surface 30 and the draw sheet or plate thereon will move at the same speed at the points of contact so there is no slippage relative to each other or the paper therebetween. In the apparatus illustrated, the blanketed roller has the blanket 8 with ends spaced apart and the portions receiving the same arranged with a space 31 therebetween, and mounted at said space adjacent the leading edge of the blanket 8 are grippers 32 that are actuated to grip the leading edge 33 of the paper sheet 1 and pull same between the draw sheet 20 and the blanket 8 as the rolls or cylinders 4 and 7 are rotated. The grippers 32 are arranged whereby the leading edge of the paper sheets fed through the machine have the same relative positioning with the printing member to accurately position the printed image on the sheet, as later described.

In the printing of images in relief on paper sheets 1, two positive plates with the images in relief thereon are produced, one of the plates being a printing plate 19 and the other an impression plate 34. The image to be printed is in the form of the character or design 35 in relief on the printing plate 19 or raised from the surface 36 thereof and the same design or image characters 37 are in raised form or extend from the face 38 of an impression plate 34. The extent of the relief of the characters on the printing plate 19 and impression plate 34 may vary due to differences in paper and the characters desired to be formed and printed therein, but it is preferred that the relief of the characters on the impression plate 34 be greater than that of the characters on the printing plate 19, as for example, the relief of the characters 35 on the printing plate 19 may be in the nature of .006 to .OlO-inch and the relief of the characters 37 on the impression plate 34 may be in the nature of .012 to .OZO-inch. The characters of the image on the printing plate 19 and the impression plate 34 are identical except for difference in relief. Also, the design or image reads direct as illustrated in FIGS. 3 and 9 respectively. The plates 19 and 34 may be made by any conventional process of providing positive plates with the image in relief thereon with the identical image on each plate, as for example the plates may be made by photoengraving from the same negative. Also, the plates may be metal or other material which may be used for printing plates in offset printing. However, it is preferred that the impression plate 34 be made of a transparent material to facilitate positioning in the desired location on the impression roller portion 6. Also, it is preferred that the copy from which the plates are made have centering designations spaced outwardly from the desired image, so that each of the plates 19 0nd 34 will have corresponding raised centering indicia 39 on margins 40 thereof.

After the printing plate 19 and impression plate 34 are completed and it is desired to print relief impressions of the image on the plates on paper sheets 1 utilizing an offset printing machine, the roll 4 is turned to provide access to the printing plate portion 5 and then a sheet of paper 41 is positioned with the leading edge 42 in the position that the leading edge 33 of the paper sheets 1 would contact the portion 5 as the sheet of paper 1 moves through the press. The sheet of paper 41 may be provided with a fold line 43 to indicate the center line so the sheet of paper can be properly positioned relative to a center designation 44 on the printing roll portion 5. The sheet of paper 41 is then secured in position as by adhesive tape 45. Then, the printing plate 19 is positioned in overlying relation to the sheet of paper 41 so that the image 35 is in the desired position or location that the image is to appear on the printed sheets. The plate 19 is then secured at one edge to the roll portion 5 as by pressure-sensitive adhesive tape 46. This permits the plate to be maintained in the proper position while it is hinged away from the roll'portion, and then the paper sheet 41 is removed and strips of double face adhesive tape 47 are applied to the surface of the roll portion over an area larger than the plate 19. After the stripping is completed, the plate is folded back so that the rear surface 48 thereof contacts the exposed surface 49 of the tape 47 to adhere the plate 19 in fixed position on the plate roll portion 5 of the press. The portions of the adhesive tape 47 extending beyond the plate 19 are then trimmed as by cutting with a knife along the edges of the plate 19 and then removing the said exposed portions from the cylinder portion 5 whereby the plate appears on the plate roll portion 5 as illustrated in FIG. 5.

Ink is distributed on the inking rolls in a conventional manner, and particularly the form roll 18, then the press is operated to effect movement of the plate roll portion 5 having the printing plate 19 thereon under the inking unit whereby ink is applied to the outer extremities of the design 35 in relief on the plate 19. The rotation is continued and the blanketed roll also is rotated without any paper sheets passing therebetween whereby the ink from the inking plate 19 is transferred as an ink impression 50 to the surface 30 of the rubber blanket 8 on the blanketed roller 7. On continued rotation and with packing 28 under the draw sheet 20 on the impression roll portion 6 of the cylinder 4, the surface 29 of the draw sheet will come in contact with the ink impression 50 to transfer an ink impression 51 from the blanketed roll to said draw sheet surface 29. The rotation continues until the portion of the draw sheet bearing the ink image 51 thereon is moved to provide access thereto, and then transparent double face pressure-sensitive adhesive 52 is applied to the surface 29 of the draw sheet covering the inked image 51 thereon. Then the impression plate 34 is arranged on the tape 52 with the image 37 in relief on the plate and the centering marks 39 registering with the corresponding parts of the inked image 51 on the draw sheet. Then, the draw sheet is lifted at one end and the packing 28 thereunder adjusted to the desired thickness for the thickness of paper 1 to be printed. The draw sheet 20 is then secured back in place on the impression roll portion 6 and the press actuated to rotate the cylinder 4 and the blanketed roll 7 feeding a paper sheet 1 therebetween.

In the structure illustrated, the blanketed roll 7 makes two revolutions to one revolution of the cylinder or roll 4 and in the revolution Where the impression plate 34 contacts the blanketed roll the sheet of paper 1 should be therebetween so as to prevent any ink from being transferred from the blanketed roll to the impression plate 34 in the production printing operations. Then, as the machine is operated, the plate roll portion 5 with the printing plate 19 thereon is moved under the inking rollers so ink is applied to the outer extremities of the relief of the image on the printing plate 19. As this printing roll portion moves by the blanketed roll 7 for that rotation of said blanketed roll, there is no paper between the rolls 4 and 7, so that the ink on the relief image on the printing plate 19 is transferred to form the ink impression 50 on the blanketed roll surface 30. On continued rotation and at the next revolution of the blanketed roll, a sheet of paper 1 is moved by the feeder into engagement with the grippers 32 so that the paper is pulled between the blanketed roll 7 and the impression cylinder portion 6 and, in said movement, the relief image 37 on the impression plate 34 engages the face 53 of the paper sheet 1 oposite the face 54 in contact with the blanketed roll 7 and in registry with the ink impression 50 on the blanketed roll. The engagement of the relief image 37 on the impression plate 34 with the paper sheet 1 forces said paper into the resilient blanket 8 so that the relief image 37 forms grooves 55 corresponding thereto in the engaged face 53 of the paper sheet and thereby the image in relief as at 56 on the face 54 of the paper engaged with the blanket 8. Simultaneously with the forming of the image in relief in the paper, the ink impression 50 on the blanketed roll is transferred to the paper to print the relief image as at 57. The first few sheets of paper passing through the machine are examined to determine that the extent of the relief image in the paper is as desired and that the relief image and the ink printed thereon are in accurate registry. If the relief is not as desired, the

amount of the packing 28 under the drawn sheet 20 is altered to increase or decrease the pressure between the impression plate image 37 and the blanket 8 on the blanketed roller 7. If the registry is inaccurate, the impression plate 34 is removed and replaced to obtain proper accuracy. If the examination shows that the printed relief image in the paper sheet is as desired, the marginal portons 40 bearing the centering designations 39 are cut from the plates 19 and 34 together with the portion of the tape 47 and 52 lying under said marginal portions and said margins removed from the roll portions 5 and 6. This trimming of the printing plate 19 and the impression plate 34 reduces them to a suitable size that carry all of the image to be printed in relief and then the structure is ready for operation to print the image in relief on the paper sheet 1. The printed relief image in the paper 1 has the image embossed and the crest of the relief printed, as illustrated in FIG. 12.

The form of the apparatus as illustrated in FIG. 13 is what 'is termed a three cylinder or roll machine 60 wherein there is an ink unit 61, a plate roll 62, a blanketed roll 63, and an impression roll 64. The printing plate 19 is placed on the plate roll 62 in a manner similar to that illustrated and described in placing the printing plate on the plate roll portion 5 of the apparatus illustrated in FIGS. 1 to 5 inclusive. The plate roll, blanket roll and impression roll each turn at the same rate and, on each rotation of the plate roll 62, the printing plate passes under the inking unit 61 and then to contact the blanketed roll 63 to transfer an ink impression thereto; The impression plate 34 is located on the impression roll 64 substantially in the same manner as it was located on the impression roll portion 6 in the apparatus as illustrated in FIGS. 1 to 9 inclusive so that on each revolution the ink impression on the blanketed roll 63 received from the printing plate 19 is in registry with the relief image on the impression plate 34 located on the impression roll 64. Paper sheets are fed by feeding mechanism 65 between the blanketed roll 63 and the impression roll 64 so that the impression roll forms the image in relief in the paper simultaneously as the ink impression is transferred from the blanketed roll to the image in relief on the paper. In such machines, the impression roll 64 has its shaft 66 suitably mounted, as for example in eccentric bearings, whereby it can be adjusted toward or away from 6 the blanketed roll to vary the pressure for squeezing the paper between the impression roll and the blanketed roll and also to vary the embossing pressure applied by the image in relief on the impression plate 34 and the paper sheet being printed.

It is believed obvious that I have provided a simple, efficient, economical manner of providing two positive plates and utilizing same in an offset printing process to print images in relief on paper sheets that results in a distinctive product.
